The “Amazing Grace” arrangement starts in the key of G, in 3/4 time. At measure 38, there is a change to the key of C and 4/4 time, which makes for a very interesting and unique performance. The “I need Thee Every Hour” arrangement has arpeggio accompaniment patterns as the lovely melody by Robert Lowry is repeated three times. In “Amazing Grace” the F levers are moved for the key change. In “I Need Thee Every Hour” there is only one lever change for Harp 1 and none for Harp 2.
